I bought this to replace a 5400RPM HDD in a laptop. The drive is lightning fast, as is characteristic of SDDs. However, be aware that although it advertises free migration utilities, you have to jump through a couple hoops. You have to make an ADATA account, register your drive, register your warranty, and after that they'll give you an activation code for Acronis Image 2015. You then have to download the Acronis program, create an Acronis account, and then activate with the code previously given before you can use the utility. It's not as bad as it sounds, but it's a pain when other companies simply have proprietary migration utilites already on the drives they sell. But hey, I guess you save a couple dollars for a reason.
